8 Claims.

My invention relates to an improvement in comb plate adjusting mechanismfor hair clippers.

The object of my invention is to provide im-' proved means for adjustingthe comb plate of a hair clipper to project or retract its teethrelatively to those of the vibratory cutter blade.

More particularly stated, it is my object to provide a hair clipperhaving an adjustable comb plate, with an operating piece for theadjusting mechanism, which can be easily reached by the thumb or fingerof the operator without shifting his grasp upon the clipper frame orcasing, and

which may be moved under light pressure to ad 'just the comb platewithout injury to the wet, tender skin of the barbers finger andwithoutdelaying the clipping operation.

. A further object is to provide for moving an adjustable comb plate bymeans of a crank mechanism so constructed 7 that the actuating arm mayextend along the side of the clipper. casing from a transverselyextending rock shaft having an interior arm loosely connected with thecomb plate, whereby a rocking movement of such arm may be transmitted tothe comb plate with minimum frictional resistance and whereby said armmay also be utilized to retain the comb plate in its adjusted positionand to indicate its position by association with an index carried by theclip per casing.

In the drawing: Figure l is a side elevation of a complete power drivenhair clipper showing the exposed portions of my comb plate adjustingdevice.

Figure 2 is an enlarged fragmentary view of the front end portion of theclipper shown in Figure 1, with parts broken away in vertical section.

Figure 3 is a section drawn to line 33 of Figure 2.

Like parts are identified by the same reference characters throughoutthe several views.

The drawing illustrates my invention as it is' embodied in anelectrically driven hair clipper. The casing It with its cap H,electrical conductors l2 and adapter or conduit I3, switch operatingpiece M, obliquely positioned movable blade 16, comb plate mounting orbase H, and adjustable comb plate !8 may be of any ordinaryconstruction, well known in the art and require no further description,except as hereinafter set forth with reference to the features ofinvention herein disclosed.

In the construction shown, the comb plate I8 is shown with a clovetailed slide l9 secured to its upper face, which may be of less widththan the comb plate and engaged in a dovetailed slide Way orgroove 2| inthe base or mounting I1. It is not material whether the slide is anintegral part of the comb plate orseparately formed and 5" attached asindicated by the screws 20. The material feature is that the comb plateis slidingly supported upon, or from the casing foradjusting movementforwardly or backwardly underneath the movable clipper blade Hi to varythe distance 10 between the clipping zone and the surface over which theclipper travels and thus regulate the closeness of the out.

In the illustrated embodiment of my invention,

a cross shaft 25 is mounted in the'base H, the 5 latter being recessedat 24 to allow a crank arm 23 to. extend downwardly from the shaft intoa suitable recess 22 formed in the upper surface of the comb plate, i.e., in its dove tailed portion or slide [9 in the construction shown.The lower end of the arm 23 is preferably spherically rounded and quiteclosely fitted within the recess 22 whereby the arm may co-operate withthe guiding portions of the base I! to. hold the base in position. 25

Oneend of the shaft 25 projects through the casing wall and is providedwith an exterior actuating arm 26 which preferably comprises a flat orhalf ovaljbar of resilient material secured to the shaft at 21 andextending along the sidewall v of the casing. Its upper or free end isprovided with a hemispherical knob 28 to be engaged by the finger orthumb of the operator for the purpose of actuating the arm andtransmitting motion to the comb plate through the associated shaft 25and arm 23. An indexed arcuate friction plate or detent 29, concentricto the shaft 25, is secured to the casing between the actuating arm 26and the adjacent casing wall. This plate 29 has stops 30 at itsrespective ends to limit the field of adjusting movements and the arm 26may be made to resiliently bear against it for the purpose ofmaintaining the adjustment pending further manual actuation of the arm.If desired, the inner face of thearm 25 may have a slight longitudinalcorrugation 3! engageable with corresponding grooves 32 in theplatewhereby to hold the arm with additional security in a desired number ofadjustments.

In the construction shown, 35 is a non-metallic cushioning pad toprevent dust and hair from entering the casing between the movable bladeand the associated casing wall; 38 is an actuating arm for reciprocatingthe movable blade l6; and 36 is a controlling button for regulating theaction of the driving motor. Neither the motor nor the controllingconnections are illustrated, and as no claim is made for the parts 35,36 and 38, further description thereof is deemed unnecessary.

I claim:

1. In a hair clipper having a shearing comb plate and a support uponwhich the comb plate is slidably mounted, the combination with thesupport, of a transversely extending shaft mounted. in the support abovesaid comb plate and provided with a crank arm having operative connection with the comb plate to adjust the same, and another armconnected with the crank shaft and extending along one side of thesupport to provide means to permit the adjustment of the comb platewhile the clipper is in operation.

2. In a hair clipper provided with an adjustable relatively stationarycomb plate clipper blade, provided with a blade guiding support, thecombination with such support, of a crank shaft journaled therein andprovided with a crank arm in engagement with the blade and an actuatingarm secured to the end of the shaft and projecting along the side of thesupport to effect adjustment of the comb plate clipper blade whentheclipper is in operation.

3. The combination with the casing, of a power driven hair clippercasing adapted to serve as a clipper manipulating handle, of a combplate mounted for sliding adjustment along one portion of the casing,and a manually operable member, movable in a plane substantiallyperpendicular to the comb plate along one side of the casing andprovided with comb plate adjusting connections within the casing abovethe comb plate.

4. In a power driven hair clipper provided with relatively fixed andvibratory cutter blades and a casing for the driving mechanism adaptedto also serve as a handle, the combination therewith of an adjustinglever supported for swinging movement at the side of the casing in aplane substantially perpendicular to the comb plate and under manualpressure exerted by the thumb or finger of the operator, and meansWithin the easing for transmitting the movement of said lever to varythe relative positions of the working margins of the cutter blades byadvancing or retracting one of them with reference to the other.

5. In a hair clipper the combination with a handle having a comb platemounting provided dle having at one end a comb plate mounting, a

comb plate adjustably secured to said mounting, a transversely disposedrock shaft journaled in said mounting above the comb plate, saidmounting and the associated portion of the comb plate being recessed,and said shaft having an arm extending through the recess in themounting into the' comb plate recess, said handle and comb platecompletely enclosing said arm and the re cesses and said shaft beingprovided with an exterior operating arm adapted for swinging move mentabout the axis of the shaft at one side of the handle.

7. In a clipper having a casing, a movable blade, a stationary blade,mounting means on which said stationary blade is adjustable to vary itsprojection beyond the front edge of the movable blade, an operatinglever mounted on the casing in spaced relation to the stationary blade,and means connecting said lever and blade for adjusting the blade, saidlever and easing being arranged to co-operate with each other to limitthe range .of movement of said lever.

8. In a hair clipper, the combination with a handle having a comb platemounting permitting sliding adjustment of a comb plate thereon, a combplate adjustable on said mounting, and comb plate adjustment mechanismcarried by the mounting including a transverse shaft in the mountinghaving an interior comb plate actuating arm loosely connected with thecomb plate and an exterioroperating arm extending along one side of thehandle to permit adjustment of the comb plate when the clipper is inoperation, said handle having an associated index gauge adapted to alsoserve as a detent to retain the arm'in various positions of adjustment.
